A Neural Network for Hyperspectral Image Denoising by Combining Spatial–Spectral Information

open access: yesRemote Sensing, 2023
Hyperspectral imaging often suffers from various types of noise, including sensor non-uniformity and atmospheric disturbances. Removing multiple types of complex noise in hyperspectral images (HSIs) while preserving high fidelity in spectral dimensions ...

Bayesian Approach in a Learning-Based Hyperspectral Image Denoising Framework

open access: yesIEEE Access, 2021
Hyperspectral images (HSI) are corrupted by a combination of Gaussian and impulse noise. Successful denoising of HSI data increases the accuracy of high-level vision operations like classification, target tracking and land-cover problem. On the one hand,
